    摘要:

    随着LED照明行业及LED驱动电源技术的发展,具有调光功能的LED驱动电源在LED照明中的应用越来越多,对其调光性能的要求也越来越高。通过对一种高效低纹波调光LED驱动频闪实现方式进行研究,使其既满足LED低纹波电流的要求,又能使LED灯在调光过程中无闪烁、亮度变化均匀柔和,并且可适应不同的调光曲线要求。

    Abstract:

    Along with the development of LED lighting industry and the technology of LED driver power supply, LED drivers with dimming function play an important role in the LED lighting applications, which also raises higher requirements for their dimming performance gradually. The strobe of an LED driver with high-efficiency, low-ripple and dimming features is studied. The novel driver not only meets the requirements for low-ripple current in LED, but also ensures that the LED lamp generates no flicker and its brightness changes evenly and softly. In addition, it satisfies the requirements of different dimming curves.
